- For Use With: Air, Beverage, Dairy, Deionized Water, Food, Pharmaceuticals, Water
- Temperature Range: See Gaskets
- Tubing:
Fittings: Use with 316/316L stainless steel that meets ASTM A269 or ASTM A270
Gaskets: Use with 304/304L and 316/316L stainless steel - Specifications Met: See table
- Certification: Material Certificate with Traceable Lot Number and Test Report
Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth. Use them in pharmaceutical and bioprocessing applications. Also known as tri-clamp fittings, they connect with a clamp, a gasket, and another quick-clamp fitting for a fast and easy way to access your line. Fittings are 316 stainless steel for excellent corrosion resistance.
Fittings with butt-weld end are also known as ferrules; they weld to tubing for a permanent connection.
The pressure rating of the fitting will depend on the clamp you choose.
The temperature rating of the fitting will vary depending on the gasket material you choose.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

Buna-N gaskets are oil resistant. EPDM gaskets resist water and steam and work well in humid environments. Silicone gaskets withstand high temperatures. Fluoroelastomer gaskets stand up to fuel, oil, and acid condensates. PTFE gaskets withstand harsh chemicals, with the exception of molten alkali metal and elemental fluorine.

Clamps for High-Polish Metal Quick-Clamp Sanitary Tube Fittings
- Temperature Range: See Gaskets or O-Rings
- Tubing:
Inch 304 Stainless Steel and Nylon Plastic: Use with welded 304/304L and 316/316L stainless steel that meets ASTM A269 or ASTM A270
Metric 304 Stainless Steel: Use with welded 304/304L and 316/316L stainless steel
Inch 316 Stainless Steel: Use with welded 304/304 L and 316/316L stainless steel
Metric 316 Stainless Steel: Use with welded 316/316L Stainless Steel
Connect quick-clamp sanitary tube fittings—also known as aseptic fittings—for a fast and easy way to access your line. Clamps with wing nut tighten by hand. Clamps with safety wing nut won’t release from minor loosening or jostling. They have a leak-before-burst design, which means they’ll leak to relieve pressure if the seal fails instead of bursting and causing a safety hazard.
Clamps with bolt tighten with a wrench. They handle higher pressures than wing-nut clamps for a stronger, more secure hold. Double-bolt clamps meet ASME design standards for pressure vessels.
Clamps with recessed nut require a hex socket adapter to loosen the nut, preventing the clamp from tampering and accidental removal. They have a hole for lockout (padlock not included) to block unauthorized access, helping you meet Hazard Analysis and Critical Control Point (HACCP) programs and Good Management Practices (GMP). Both of these security measures reduce the risk of product contamination. These clamps have a leak-before-burst design, so rather than burst dangerously if the seal fails, they’ll safely relieve pressure by dripping instead.
304 stainless steel clamps have very good corrosion resistance.
316 stainless steel clamps are more corrosion resistant than 304 stainless steel clamps. Clamps with two-pin hinge apply more even pressure on gaskets than other clamps, causing less wear and tear on gaskets.
Nylon clamps are lightweight compared to stainless steel clamps.

The temperature rating of the fitting will vary depending on the gasket or O-ring material you choose. Buna-N is oil resistant. EPDM resists water and steam and works well in humid environments. Silicone withstands high temperatures. Fluoroelastomer stands up to fuel, oil, and acid condensates. PTFE withstands harsh chemicals, with the exception of molten alkali metal and elemental fluorine.
